Asslenons GAS-RANGE.

To all whom t may concern:

Be it known thatwe, HENRY D. .SCHALL and RaNsoM W. DAVENPORT, bothcitizens of America, residing at the United States of Detroit, in thecounty of rayneai'id Sta-te of Michi an, have' invented certain new andis an object to facilitate the lightin of the' burner and the easydetachment of t e same for cleaning.

In the drawings:

Figure 1 is a perspective view of a gasl range to-which our improvementsare applied;

Fig. 2 is .a sectional plan view thereof; Fig. 3 is a longitudinalsection through the lighter for the burner;

Fig. 4 is across section thereof.

- s ln the present state of the art, with certain types of 'gas range itis customary to use a single burner for heating the bottom of one oven vand the top of the broiler or toaster oven. To distribute the heatuniformly over thetbottom area it is usual to have a plurality ofburnery jet tubes in the form of a U- tubel or otherwise connected to becontrolled froma single burner. This, however, has the disadvantagevthat it is diiiicultto obtain a low fire on account of the large openjet areaffurthermore, as is usually 'the' case, where the controllingvalve is at the side o f the oven it is diilicult to see the flame whenmanipulating the valve. With our improved construction this defect is.overcome, first, by substituting two independently-controlled burnersfor the single-control U-tube burner, and the easy manipulation is alsofacilitated by placing the controlling valves for both` burners 'at thefront rail of the stove or in alineinent with the burners controllingthe open top.

is the open top section, C is the baking oven arranged at one side ofthe open top and above the same, and D is the lower or broiler ovenbeneath the. oven vC and at the-side of thepan or casing beneath theopen top. The ovens C and D are separated from each other by asheet-metal partition E which is removmeiits into one. At the front ofthe open top section is arranged the usual gas supply tube controlled byvalves H H', etc. The valves H? and H5 with` the tube and -inalii'iement with the valves for the open top burners at the end adjacentto the oven. I and I' are gas tubes leading from the air-mixing chambers.l into series of burners G G', etc'.y

coinpart for controlling the broiler and oven burner are also arrangedinconnection the compartment beneath tiif-o en top and then extendinglaterally vat and K' through the side Wall L of the oven and con-Anecting therein with the burners M and M',

lThe opposite ends of these burners are supported upon a bracket N,while the tubes I and 1" in passing into the oven are supported on theslotted plate O clamped by' a thumbsorew to the side of the oven wall.This thumb-screw passes through a` slot P' in the plate, which permitsof a longitudinal adjustment thereof, the purpose of which is to engageand disengage the ends of the tubes l andl Ivwith the nozzles of theirrespective To facilitate the lighting of the burners M and M', we havearranged a pilot and lighter tube Q which extends centrally from oneburner to the other and extends forward in the oven to the front endthereof. This tube Q is preferably a cored casting having apertures Rand R therein for engaging upwardly-projecting nipples S on the burnersM and M', thereby forming a gas connection. There is also a slit Tformed by sawiiig which extends longitudinally of the tube Q so that byigniting the gas at the front of the tube the fiame will run along theslit to each of the burners M and M'. Also this tube opera-tes toautomatically light one burner from 'the other.

yWith the construction as described, to attach and detach the oven andbroiler burners they are irstengaged with the slotted plate 0, and theburners proper are inserted I l through `the vapcrtuied side L of theoven As shown, A is the frame of the stove', B

Thus whenever it is neceenryto clean the burners they may be quie ly removed und re laced.

Thetnbe Q is also quickly assemble With the burners by merely engagingthe leperturee R and R thereof with the niyples S yand at any time whenthe burners 'are to be remover? it may be lifted therefrom.
